For the base of the cake, I used two 9-inch round cakes, fitting them together by cutting off a small wedge from the joining sides. (I made a race track cake in this fashion for Jack’s second birthday, and I thought that figure eight shape would work perfectly for a train track, too.) Using a basic white cake mix, I made a pan’s worth each of dinosaurs and trains. Jack wanted his dinosaurs to look just like the characters from the show, so I separated the prepared batter into several bowls to mix in a bit of gel food coloring before I poured it into the pans. I made orange, blue, green and purple. The purple turned out to be a very odd looking color once it was baked, but thankfully no one else seemed to notice.
4 Before you begin frosting your cake, add a dab of frosting to the cake board and place your base cake on top. The frosting will act as a “glue” of sorts, anchoring the cake to the board as you work to keep it from shifting around.
7 I know this sounds cliché, but have fun! And try not to worry about the mess you make in the process.
